Hi There, Just a one day procedure so I'm back home. a little sore and shaking but doing ok. Had an old military injury, was in a patrol vehicle, hit a land mine, had my face smashed a bit against hard surface. All front teeth broken, jaw cracked, nose squashed and left cheek bones crushed etc. Seems after years scar tissue extended and closed off all drainage from left side sinuses. Lots of infection and build up in left sinuses causing all kinds of poisons and headaches so I bit the bullet and had it repaired and cleaned. Hope it works out ok. Getting old is not for sissies.

Done some testing again this morning. I'm convinced the Alto is not working on the recording side of the USB. This is my reasoning.
1 Win 7 Sound Playback set to USB Audio Codec, Level 100.
2 Win 7 Sound Recording set to USB Audio Codec, Level 100.
3 Tested the Windows Accessories Sound Recorder it is not getting anything for the mic plugged into the Alto. (Phantom power is on)
Got BIAB and RB Options for Audio both set to MME Drivers on USB Codec.
4 Is it the Cable. I have 2, both do the same on the Alto, both work perfectly on the Wharfdale.
5 Is it the USB Port on the PC. Not the PC because the Wharfdale works so could be the USB Port on the Alto.
6 Got the USB In selector on the Alto set to Control.
7 Got the headphones plugged into the Alto selected Control.
8 Loaded a SEQ file in RB. Hit play and I hear the music.

The VU meter at the bottom shows Output movement.
I try the Mic in the Alto set around 0db. I see activity on the Mixer VU meter, if i switch the headphone to Main I hear the mic and no music. The VU meter on RB shows no activity at all. If I understand the Mic should be going via the Main Mix from the Alto through the USB Driver/Cable into RB and show activity on the VU Meter in RB. Nothing there.

I close RB and open BIAB. All same settings same results.

Switch to the Wharfdale mixer and the same testing again. Now everything works.

Like I said before I'm convinced the Alto is faulty on the Main Out to the PC.
Going to take my meds now and back to bed.
Take Care. Bryan.
